Science Investigatory Project
ABSTRACT
The title of our project was Bilimbi fruit as an alternative stain remover. The purpose of this experiment was to find out if Bilimbi can remove stains from our clothes. We all know that teenagers today are very eligible especially in wearing dress. We conduct this kind of study to be able to have another background study about natural bleaching agent and to build natural product that is a solution for a stains The procedure involved was to apply the extract of Bilimbi to the clothes were the stains are located. The Bilimbi was divided into two pieces and brush it to the clothes were the stains are there. There are 3 trials in the experiment. The experiment was observed for 10 minutes. The result of the experiment was recorded on different types of stains. We repeated these steps for 3 types of stains. The result of these data resolves that Bilimbi can remove stains like sauce and rust but it cannot remove through an ink of a ball pen. Our experiment also concludes that the Bilimbi can remove stains but some can’t. In conclusion the Bilimbi can remove stains more in sauce. The Bilimbi fruit juice has a high concentration of oxalic acid which is useful for cleaning and bleaching.
